The Model 112 features a unique two-tier design that isolates the amplifier section from the power supply. This serves to keep the sensitive amplifier circuitry shielded from the electrically noisy power supply. Unlike other “audiophile” amplifiers, the Rowland Model 112 avoids the temptation of breaking the amplifier into two (or four, for monoblocks) chassis. The Model 112 is an integrated product with a purpose.
